My invention is particularlyyintended to be: applied to oven burners and is an 'improvement upon the construction of oven burners and :support shown initheapplica tion of Caverly'and'Bell, Serial No. 874,961,

filed December 1, 1914, but is not limited in its usefulness thereto.

Specifically'my invention comprises a for- Wardly and downwardly sloping shelf-at the rear ofthe frame upon which 'rjests'a correspondingly inclined lower surface-at the rear of the burner, the forward end of the burner'being slida'blymounted upon the gas inlet nozzle connected to the manifold in front of the range, the sloping supporting shelf having a forwardly extending slot therethrough, in which slidably engages a downwardly extendinglug' at *ther'ear of the With thisconstruction, the burner.

burner. can only be applied in proper position, as otherwise it will fall off the shelf, and the provision of the forwardly sloping engaging surfaces of the rear supporting shelf and burner causes the burner to press forwardly upon the gas inlet nozzle, regardless of the contraction and expansion of the parts under temperature changes, a slight longitudinal movement of the burner under Working conditions being permitted by the lug andslot engagement referred to at the rear of the burner.

Other features of my inventionwill appear in the following specification.

Patented Dec. 7, 1915. SerialNo. 16,323. i invention may be had, attention is he reby directed to the accompanying drawings formlng part of this application and illustrating the preferred embodiment of my invention.

In the drawings Figure 1 represents a vertical longitudinal section through aburner mounted inpositionadjacent to an oven in a gas range, the frontand rear frame members being 'shown'broken away, andFig. 2 is arearelevation of the burner disconnected from its supports. p

eferring to the drawings, the burner 1 isof cast iron construction of pipe shape, cored and, drilled as usual and provided with an air mixer cover indicated M2. The burner is slidably supported at its rrofic end on the gas inlet nozzle 3, which is connected by tl'ie usual cocki, to the inanifold 5, which latter is supported by a suitable bracket 6 from theoven front 7. The portion of the frame construction illustrated at m n-{om of the oven is similar tothat illustrated in application of Caverly and Bell already referred 'to. Int-his construction, as 1llustra'ted,a heat deflector or insulatioh member is 'fastened'to the oven front 7 inthe portion thereof through burners extend, this comprising asheet of metal 8nwhich is notched atthe cornersand formed into a pan with flanges 9 at the ends. It has holespierced therein for burnerf cups, one ofwhichisillustrated at 10, whichare made of drawn sheet-metal electricwelded to flanges formed on member 8 along curved V 8. Member 8 may the cups and the member beheld in position by, electric welding-its flanges 9 to the oven front 7, or by other suitable means.

The construction represented has a rear wall 11 and a rear vertical lining member, the slanting support for the rear end of the burner or burners being secured to member 12. This support comprises a bent metal bar having a vertical portion 13 and a forwardly extending and downwardly slanting shelf 14:, the vertical portion 13 being secured to the sheet-metal lining member 12 by means of bolts or other securing means 15, a steel angle 16 preferably being provided on the rear side of member 12 for stiffness, bolts 15 extending through members 13, 12 and 16. The sloping shelf 14 is which the provided with forwardly extending slots 17, equal in number to the burners which are to be supported.

Each burner pered lug 18 projecting downwardly from the rear end of the same and seated within slot 17 when the burner is mounted in position, slot 17 being'somewhat longer than the thickness ofthe lug 18 engaged therein to permit lengthwise movement of the burner. The surface of burner 1 from which lug 18 projects is a plane surface, as shown at 19, extending on each side of the lug 18 and slanted with the same inclination as the shelf 14. Preferably, the rear end of the burner is formed on its upper side as indicated at 20, with a slanting projection, this insuring that the burner will not be mounted up-side-down on burner is mounted in position as shown, the

slanting flat surface 19 thereof provides a firm support on the shelf 1a so that the burner will not rock, and the inclination of surface 19 and shelf li tends to press, the burner forwardly so that the front end'wall 21 of the burner will press as far forward on 3 as possible, insuring a the gas inlet nozzle tight joint. I

The enlarged portion 22 of the burner is preferably provided with an upwardly extending lug 23, which slidably engages within a recess 2 f formed in the upper portion of burner cup 10, direction of the burner 1 and fitting the lug 28 fairly closely. The forward portion of the burner is also preferably provided with a downwardly extending lug 25 whichengages the bottom surface of burner cup. 10 when the burner is in position. These devices aid in rendering wrong application of the burner impossible. The burner may be removed by simply moving the same rearwardly and raising the rear end, the length of slot 17 and the shape of lug 23 and the burner cup '10 permitting this. When the burner is in position, it is evident that contraction and expansion of the same under copies of this patent may be obtained for l is, provided with a tafold in the shelf 1%. When the 2. In a gas forwardly and downwardly sloping supthis recess extending in the *ariations of temperature are permitted, while at the same time the provision of slanting surfaces 19 and 1a insure the burner always being pressed forwardly into its proper position. 7 p

Having now particularly described'my invention, what I claim and desire to protect by Letters Patent is as follows: 7

1. In a gas range, the combination of an oven having a rear vertical member, a metal shelf comprising a vertical portion secured to said member and a forwardly extending, downwardly sloping flange having a forwardly extending slot therethrough, a manifront of said oven having a gas nozzle directed toward said range, and a burner slidably mounted at its forward end upon said nozzle, and having a sloping lower surface atits rear end resting upon said sloping flange, and a lug extending downwardly into said slot to have sliding engagement therein, substantially as set forth. 7 range, the combination of a port, a'gas inlet pipe, and aburner slidably mounted on its forward end upon said pipe,

and having'a sloping lower surface adjacent its rear end resting upon said sloping support, the coacting surfaces of said burner and support being plane surfaces of. corre-- sponding inclination said support having a forwardly extending slot therethrough, and the sloping supporting surface of said burner having a lug extending downwardly into saidslot to have sliding engagement therein, I

said burner having a lug extending transversely therefrom, at the forward end, and a frame member having a recess in which said lug is closely slidably engaged, substantially as set fort i "This specification signed and witnessed this 19th day of March, 1915.
